I only care about sound quality and iPods usually aren't the best so it's nearly irrelevent to me. It seems the more they pack in, the worst the quality gets IMO. I don't use a lot of space since I manage my songs weekly with only 1GB of space so any of these models would do. If I wanted to put all my music on there, I couldn't since 160GB is still not enough to have all of it. I'm most interested in the touch only for the photo application. It would be most impressive to show potential clients.

I think the lack of HD on the iPod touch is gonna haunt them more than they think. Sure the iPod touch is super thin, but I'd rather have 160gigs than quarter of an inch thinner. It's gonna fit in my pocket either way.
